[Swansea Hackspace] New Project - Powerpack for a laptop

[Ceri Clatworthy]

Big ask to charge laptop
my phone If I remember 450 mA
tablets about 1 to 1.5 Amp

Laptop could be 3 - 4 Amps

as for a battery, then a some 18650 type batteries ?? 40000 mA/H  (4 A/H)
 !!!!!!!!!!!!!!!

although some *serious *power path management will be required,

and a good level of safety - electrical, mechanical will be needed,

because in the wrong hands, it's an incendiary device !!
